Continuous level measurement in liquids and solids with free space radar sensors

​

Radar level measurement with top-down installation of a Micropilot sensor offers perfect application fit in all industries. Non-contact radar with simple commissioning, trouble-free operation saves time and money. For usage in a wide range of applications - be it in simple storage tanks, in corrosive or aggressive media or high accuracy tank gauging applications.

Radar level measurement is a safe solution even under extreme process conditions (pressure, temperature) and vapors. Micropilot can also be used in hygienic applications for non-contact level measurement. Micropilot versions are available for different industries like water/wastewater, the food industry, life sciences or the process industry. Various antenna versions for every kind of radar application are available.

 

Radar measurement: Measuring Principle

​

Micropilot works with high-frequency radar pulses that are emitted by an antenna and reflected from the medium surface due to a change of the dc value (relative dielectric constant). The Time-of-Flight of the reflected radar pulse is directly proportional to the distance traveled. If the tank geometry is known, the level can be calculated from this variable.
